The units with multi refrigerant circuits from to 152 kW have outstanding benefits that
make this product effective for a variety of applications. The units are shipped from
the factory completely ready for installation and use. Each unit is pressure-tested,
evacuated, and fully charged with R410A, and has an initial oil charge. After
assembly, a complete operation test is performed with water flowing through the
cooler to assure that the refrigeration circuit operates correctly.
The units can be installed on the rooftop, ground outside and so on instead of being
equipped within a special machine room. It can be widely applied in new built or
reconstructed industry and civil-building project, such as hotel, apartment, restaurant,
office building, shopping mall, theater, gymnasium, hospital and so on, as well as
supplies required cooling water for factories in technical process of producing, so it's
especially suitable for some special locations around where there are high-level
requirements for noise and environments and cooling tower are difficult to install.

3.1 Brief Introduction
FEATURES

LS QW R F 80 M G/Na C -F
By using multi compressors on each chiller, unloading characteristics and part load
performance are outstanding. Integrated part load value (IPLV) is a part load
performance indicator as outlined in ARI Standard 550/590-1998. The IPLV rating
compares the performance of different chillers under identical conditions. When the
IPLV is listed in EER (Energy Efficiency Ratio), a higher EER will indicate that the chiller's
overall performance is better.
The chillers have a reputation for a compact design and small footprint. A small
footprint can save installation costs by minimizing the size of the concrete mounting
pad or reduces the amount of structural steel if the unit is mounted on the rooftop.
The chillers are designed with quiet scroll compressors. Fans are selected for good
performance and lower sound levels. The attention to detail with sound is critical in the
design. Small issues such as refrigerant piping, supports for piping, securing
components to the structure are all important to making a quiet product. We proudly
publish our sound performance.
Quiet Operation
Excellent Part Load Performance
Compact Design with Small Footprint
4GREE Central Air Conditioners
Utilizing new scroll compressor technology, the chillers meet or exceed the
performance requirements of ASHRAE 90.1. All system components are selected for
optimum performance, including the condenser coil areas and evaporator sizes.
High Efficiency Full Load Operation
3.2 Standard Specifications
GREE has provided the latest technology in controlling the chillers. The new controller
provides auser friendlyenvironment for the operator. The control logic is designed
to provide maximum efficiency, to help provide continuing operation in unusual
operating conditions through proactive controls, and to provide a history of conditions
to aid in problem resolutions. Perhaps the greatest benefit is the Protocol for
integrating with your building automation system (BAS).
Superior Controls
Compressors
These rugged hermetic compressors are constructed with an integral cast iron frame,
cast iron scrolls, three Teflon impregnated bearings, and three oil filtration devices for
each compressor. One to thity-two compressors can run, depending on the load of
the system, resulting in excellent Part-load efficiency. Each refrigerant circuit has
specially designed oil and gas equalization lines to control oil migration.
The design also offers radial and axial compliance, a large internal volume for liquid
handling, a removable suction screen, and a rotary dirt trap and oil screen. In
addition, the compressor is self-compensating for wear, handles moderate liquid
slugging, and inherently yields high efficiency.
The evaporator is direct expansion, shell-and-tube type with water flowing in the
baffled shell side and refrigerant flowing through the tubes. Two independent
refrigerant circuits within the evaporator serve the module's dual refrigerant circuits.
The evaporator has a carbon steel shell and seamless high efficiency copper tubes
roller expanded into a carbon steel tube sheet. Refrigerant heads are carbon steel
with multi-pass baffles to provide oil return . For water removal, 10mm vent and drain
plugs are provided on the top and bottom of the shell. An ambient air thermostat
controls the heater cable. The fitted and glued in place insulation has a K factor of
0.28. The refrigerant side maximum working pressure is 4400 kPa. The water side
working pressure is 1048 kPa. Each evaporator is designed, constructed, inspected,
and stamped according to the requirements of the ASME Boiler and Pressure Vessel
Code.
Evaporator
Condenser coils have internally enhanced seamless copper tubes arranged in a
staggered row pattern. The coils are mechanically expanded into flat aluminum
fins with full fin collars. A variety of optional coil material and coatings are
available for corrosive atmospheres.
Fans-The condenser fans are composed of corrosion resistant aluminum hub
and glass-fiber-reinforced polypropylene composite blades molded into a low
noise airfoil section. They are designed for maximum efficiency and are
statically and dynamically balanced for vibration-free operation. They are
directly driven by independent motors, and positioned for vertical air discharge.
The fan guards are constructed of heavy-gauge, rust-resistant, coated steel. All
blades are statically and dynamically balanced for vibration-free operation.
Motors-The fan motors are totally enclosed air-wver, squirrel-cage type. They feature
ball bearings that are double-sealed and permanently lubricated.

This well protected compressor includes a solid-state motor protection module, 4
individual motor winding sensors, a patented internal discharge temperature probe,
and a patented shutdown feature that prevents reverse rotation. An internal
discharge check valve helps prevent shutdown noise and comes standard with high
and low pressure taps with Schrader valves, a sight glass, an oil level adjustment valve,
and an off cycle crankcase heater.
Unit on-off switch: ON-OFF switch is provided for manually switching the unit control
circuit.
Indicator lights: LED lights indicate power on to unit, running state and fault indications
due to safety devices.
Filter: Refrigeranting circuits are kept free of sludge, acid and oil contamination with it.
Under voltage and phase protection: Protects against low incoming voltage as well as
single phase, phase reversal.
Liquid line solenoid valve: IT coses when the compressor is off to prevent any liquid
refrigerant from accumulating in the evaporator.
3.3 Standard Accessories
6GREE Central Air Conditioners
3.4 Standard Control & Safety Devices
The chiller's Unit Control Module is an innovative, modular microprocessor control
design. It coordinates the actions of the chiller in an efficient manner and provides
stand-alone operation of the unit. A Human Interface Panel is a standard component
of the Chiller. Access to all unit controls is via the Human Interface Panel.
Safety valve: Protects the unit against high discharge pressure.
Compressor In-built protection device: Motor winding temperature, discharge gas
temperature and phase reversal for direction of rotation.
Crankcase heaters: Protects the unit against refrigerant migration, oil dilution and
potential compressor failure.
High pressure switch: Provides protection in case of excessive discharge press-ure.
Low pressure switch: Provides protection in case of unsafe low suction pressure.
EER=Energy Efficiency Ratio at full load-the cooling capacity in Btu's per hour(Btu/h)
divided by the power input in watts, expressed in Btu/h per watts((Btu/h)/watt).
